1. DESCRIPTION
1.1. General
The Compac 3000 is a microprocessor-based circuit board designed for use in liquid and
gaseous fuel metering. It is suitable for commercial, retail, and bulk-metering applications
and can be used for Tank Gauging, card reader access, and many other control functions.
All descriptions, tables, graphics and drawings in this manual relate specifically to
Issues 'L', 'M' and 'P' of the C3000 PCB.
Figure 1. Layout of C3000 Printed Circuit Board
The C3000 microprocessor, commonly referred to as the 'head', is powered by an
intrinsically safe power supply, and is designed to operate in both a class 1 zone 1 area and
in the vapour-proof box 1.2m above the ground level. If the ‘head’ is used in a class 1 zone 1
area then the power supply and the 230V output circuitry is encapsulated.
The C3000 ('head') performs the following functions (depending upon which accessories are
connected):
•Converts the rotation of a meter into pulses via the Compac Encoder.
•Converts these input pulses into litres.
•Controls the operation of an electric motor or a submersible pump.
•Controls the Preset Valves.
•Provides Temperature Compensation to the litres value.
•Provides Meter correction.
•Provides an electronic 'K-Factor' for calibration. This means that the unit can be used on
any type of meter, regardless of turns per litre.
•Can be fitted with a card-reader directly on the dispenser/pump to give unattended 'fleet'
type access.
•Can be fitted with a PIN / Odometer pad, with or without card reader, on the
dispenser/pump.
•Can be plugged into the Compac Modem Package (Futra only).

1.2. Safety Precautions
The C3000 head, and its associated circuits and wiring, is certified electrical equipment
approved for use in a hazardous area (Class 1 Zone 1, Group IIA T3). Only parts identical to
those covered by the certification may be used where the integrity of the intrinsic safety may
be affected. All circuit boards are only to be repaired by Compac Industries Ltd.
1.3. Static Electricity Precautions
Electronic components used are sensitive to static. Please take anti-static precautions.
All circuit boards must be carried and transported in static-shielded bags. An anti-static wrist
strap should be worn and connected correctly when working on any electronic equipment. If
an anti-static wrist strap is unavailable, or in an emergency, hold onto an earthed part of the
pump/dispenser frame whilst working on the equipment. This is not a recommended
alternative to wearing an anti-static wrist strap.

COMPAC INDUSTRIES LIMITED C3000 SERVICE MANUAL SET-UP MODES
23/03/04 Page 9
3. SET-UP MODES
To enable the C3000 to operate as desired, 3 things must be set:
1. Operating Dip Switches
•A Block of 4 sliding switches.
2. Configuration (K Factor) Switch Settings
•This switch accesses different options that must be set appropriately for the particular
type of dispenser.
3. Parameter Switch Settings
•This switch is used to conduct the Display Segment Test, set price (product density - if a
bulkmeter), and set pump number. Also, when the C3000 is configured for 'Comcard',
'Compin', or 'CWIDKey' the parameter switch is used for card/pin/key validation and for
setting the card/key system number (access code - refer section 3.4.8).
•With CNG dispensers, the sequencing rate between 'banks' is also set using the parameter
switch (reference section 3.4.6).
The positions of the above switches are shown on Figure 1, page 4. Also, note that a second,
more readily accessible parameter switch is mounted in all pumps/dispensers. This gives
quick access for service station staff to make changing price easier. Set up of the C3000
must be done in the following sequence:
1. Operating Dipswitch Settings (power OFF the C3000 before changing)
•To be set, before 'powering up'.
2. ‘K’ Factor Switch Settings - starting with configuration setting and moving back through
the options to the K Factor setting:
‘K’ Factor Switch Settings
Setting Price Display Litres Display Reference
Configuration Code ‘C’ ‘XXXXX’ Refer section 3.2.8.
Display Resolution ‘Sr’ ‘X.XX’ Refer section 3.2.4.
Temperature ‘E’ ‘E XXX.X’ Refer section 3.3.3. LPG and
Bulk-metering only

SP: Set decimal place. Appears only when the unit is set-up for CNG.
NOTE: The K Factor setting should be done last of all (i.e. until parameter switch settings are
made, the pump/dispenser may not be operational, and so a calibration fill may not be possible).
3. Parameter Switch Settings - all must be set, but order of set-up is not critical.
3.1. Operating DipSwitch Settings
The location of the block of four DipSwitches on the Processor Board is shown in Figure 1
on page 4.
Dipswitch ON/OFF Brief description of dipswitch function
1OFF Display Error checking on.
ON New style displays (Use 8x1 pinheader connections)
2OFF Normal operation
ON Comcard or CWIDKey Basic systems
3OFF Normal operation. (Pump start is controlled by the nozzle switch)
ON Auto-authorise mode. (Pump starts on being authorised)
4OFF Will operate “stand alone”. (does not require a controller)
ON Requires the presence of a controller to start the pump.
3.1.1. Switch 1
If Switch 1 is OFF, the display will automatically check the data.
•Dollars
•Litres
•Price
NOTE: In order to use an old style display, wiring modifications must be done if it is to be used
on Issue "L" and/or Issue "M".
If Switch 1 is ON, the latest type Commercial, Retail, or Multi-Purpose displays are being
used.
•Litres
•Dollars, Litres, Price
•Litres, Rate of Flow, Preset
NOTE: The old type of display pin is a 6 x 2 (Issues A thru E) and the new type of display pin is
an 8 x 1.
3.1.2. Switch 2
If Switch 2 is ON, the head is set up for Comcard Basic, or CWIDKey Basic, which are self-
contained systems operating independently of any controller.
•To operate, a card-reader/CWIDKey reader must be plugged into the 'head' and the
correct access code and card/key number validations must be set by the Parameter switch.
If Switch 2 is OFF, the system will function as a conventional dispenser/pump.
•For the Bulk Meter Register, Switch 2 must be off. Comcard, and CWIDKey Basic
systems are not available in this mode.

COMPAC INDUSTRIES LIMITED C3000 SERVICE MANUAL SET-UP MODES
23/03/04 Page 11
3.1.3. Switch 3
If Switch 3 is ON, then dispenser/pump software will run in AUTO AUTHORISE mode of
operation (used for wharf & aviation sites, or any other sites where the hose reel is remote
from the pump unit):
•The pump/dispenser will start automatically after it has been initialised by the card-
reader or remotely by a Compac controller.
•The dispenser/pump will switch off after four minutes if flow does not commence.
•The pump/dispenser will switch off XXX seconds after flow rate stops.
°This can be adjusted to clients' requirements, between 1 and 255 seconds.
•The nozzle switch becomes a shut-off switch (i.e., The nozzle switch can be replaced
with a stop pushbutton or normally closed toggle switch).
NOTE: In AUTO AUTHORISE mode the nozzle input must be shorted out.
If Switch 3 is OFF, then the pump/dispenser software defaults to conventional operation,
(i.e. The nozzle switch controls the pump start after initial authorisation).
CNG Only: If switch 3 is OFF, the solenoids stay on at the end of sequencing until the refuelling assembly is
returned to its holder, at which point all outputs turn off. With this switch ON, all the solenoids turn off at the
end of sequencing.
3.1.4. Switch 4
The function of Switch four (4) depends on whether the head has been set up as one of the
Basic Systems (Comcard, Compin, or CWIDKey) or a conventional pump/dispenser, using
Switch two (2).
•Basic Systems:
With all Compac pumps/dispensers, the 'head' will display the dollars and litres grand
totals when the nozzle switch is pressed quickly five or more times.
NOTE: On a commercial pump/dispenser with litres-only display, only the total litres can be
read.
If the 'head' is set-up as a Comcard, Compin, or CWIDKey Basic system then, after
displaying the grand totals as above, the head will also printout the totals for each
card/pin/key, irrespective of the switch 4 setting.
By placing dipswitch 4 ON, the 'Scrolling Totes' option is selected (See section 5.2
page 28). In this mode of operation, after printing the totals as above, the 'head' will
flash card totals on the pump's main display. All non zero card totals are displayed
consecutively, for 10 seconds each.
NOTE: The totals can only be zeroed by replacing the memory chip.
•Conventional Pump/Dispenser (Switch 2 OFF)
If Switch 4 is OFF, the pump/dispenser can be operated in 'stand-alone' mode
irrespective of the pump/dispenser number loaded.
If Switch 4 is ON, the pump/dispenser will not work in 'stand-alone' mode, (i.e., it
requires initialisation from a controller).
NOTE: The pump/dispenser ceases to work in 'stand-alone' mode if dipswitch 4 is ON and it is
connected to a controller. Generally on retail forecourts, this switch should be left off. Hence, if
the forecourt controller breaks down, the dispensers/pumps can be set to work in the 'stand-alone'
mode simply by turning them OFF for 1 minute minimum, then back ON.
However, for unattended situations (e.g. truckstops), the pumps must not be left able to work in
the 'stand-alone' mode in case of a controller failure. Therefore, dipswitch 4 must be left ON.
For the Bulk Meter Register configuration, when Switch 4 is OFF, the unit will work in the

COMPAC INDUSTRIES LIMITED C3000 SERVICE MANUAL SET-UP MODES
23/03/04 Page 12
'stand-alone' mode. When Switch 4 is ON, the unit must be connected to a Compac Central
Controller.

3.2. 'K' Factor Switch
The 'K' Factor switch is located on the C3000 PCB as shown in Figure 1 on page 4. The 'K'
Factor switch is used to access and change various set-up options of the C3000 head. The
following flow charts detail the operation of setting up the C3000 head:
Any change of set-up effected by the 'K' Factor switch takes effect as soon as the C3000
resets. The power supply does not have to be interrupted.
NOTE: The C3000 will reset at any stage during the 'K' Factor switch operation if the switch is not pressed for
a period exceeding ten (10) seconds. If the C3000 resets out of any field before the numbers have been set
correctly, then that field must be entered again to ensure the details are correct.

3.2.2. Calibration ('K') Factor
(See also section 10.3.11 for more information on the encoder/pulser)
The 'K' Factor is a ratio of litres dispensed per revolution of the meter.
To follow is the method of calibration, including how to calculate the new 'K' Factor and
how to enter it in the C3000 memory.
Calibration
To calibrate the dispenser/pump, dispense fuel into a certified measuring container, and
compare the display value with the amount dispensed.
Example:
Display shows 10.00

COMPAC INDUSTRIES LIMITED C3000 SERVICE MANUAL SET-UP MODES

Note: Once the dispenser/pump resets with the correct 'K' factor entered, the display will show the new
volume unless the 'head' is in Compensation mode, in which case the display volume will not change (see
section 3.2.5).
Caution: Be careful when calibrating dual or multi-hose pumps & dispensers to ensure that the correct 'K'
factor is being changed.
3.2.3. No Flow Cut-Off Timer
Under normal conditions to end a transaction on a C3000 controlled pump/dispenser, there
are three possibilities:
•Returning the nozzle to its holder.
•Reaching the preset amount entered.
•Cut out on the 'No flow cut-off timer'.
The No Flow Cut-off Timer sets the amount of time the dispenser/pump will allow a sale to
continue after the flow has stopped. The No Flow Cut-off Timer is terminated if the nozzle is
returned to its holster.
The range available is between 1 & 256 seconds. The default setting is 'n0000'(256
seconds).
Setting the No Flow Cut-Off Timer
Refer to section 3.2.1 page 13. While setting this value the price display will indicate ‘n’ and
the volume display will indicate ‘nXXXX’.

3.2.4. Display (Litres) Resolution
For standard dispenser/pumps, high flow dispenser/pumps & bulk metering, different
resolutions are often required:
Display Type
Display Resolution 5-Digit 6-Digit
Standard (default) 0.00 0.000
Hi-Flow 0.0 0.00 See Note 2
Bulk-metering N/A 00000.0
000000
000000[0]
[0] is not displayed
NOTES:
1. Displaying of three decimal places is only available when six digit displays are used.
2. When the resolution is set to one decimal place (0.0), the preset display is for four whole digits. The
standard is three digits for a retail display (i.e. the maximum presetable amount is then 9999 litres
instead of 999 litres).
3. As well as displaying the decimal point, a full colon will show on the display after 'power on', until the
first transaction is started (i.e. the display shows ‘:0.0’ until the first new transaction begins).
Setting the Display Resolution
Step ACTION RESULT
1Ensure that the nozzles are hung up Dispenser in idle state
2Press and release the ‘K’ Factor switch
continuously until the Litres resolution
is displayed
The price display indicates ‘Sr’ and the
Litres Resolution is displayed as “0.00”
(standard resolution on 5-digit display)
3Press and hold the ‘K’ factor switch. The decimal point will begin to move.
4When the resolution (decimal point) is
correct, release the ‘K’ Factor switch.
NOTE: the C3000 will reset itself if the ‘K’
factor switch is left for more than 10 seconds.
3.2.5. Solenoid Delay
The Solenoid Delay was installed in the program to enable the "delay" between the
submersible pump operating and the dispenser solenoids operating to be controlled on initial
start-up. This setting should only be set on dispensers.
This setting should never be set more than 4-6 seconds. Its main purpose is to allow the leak
detector on the submersible pump to carry out its leak test.
The default setting is 'd0000'(i.e., no delay). All dispensers with a self-contained pump
should be left at the default setting.
Setting the Solenoid Delay
Refer to section 3.2.1 page 13. While setting this value, the price display will indicate ‘Sd’
and the volume display will indicate ‘dXXXX’

COMPAC INDUSTRIES LIMITED C3000 SERVICE MANUAL SET-UP MODES

3.2.6. Pre-Set Cut-Off
Pre-set Cut-off is available from Software Version 26:01.0.
Prior to the dispenser reaching its preset amount, the solenoids are switched to give a low
flowrate. The “preset cut-off” sets the amount (in litres), prior to the preset amount being
attained, at which the solenoids will switch to a low flowrate.
With the value set to 0.00, the default values are used. These are:
°LPG 0.75
°Oil 0.05
°Other products 0.32
The Preset Cutoff is calculated as follows:
[Price per Litre] X [over-run (displayed as a dollar value)] + default value as above
Example:
Price per Litre = $0.96
Dollar amount of fuel required = $20.00
After delivery price display shows: $20.01 ($0.01 is the over-run dollar value)
New preset = (0.96 x 0.01) + 0.32 (Other Products) = 0.3296
0.3296 rounded up = 0.33
New preset cutoff to be entered is 0.33.
Setting the Pre-Set Cut-Off
Refer to section 3.2.1 page 13. The Price display shows 'PCut' and the volume display
shows 'PCX.XX'. The range is from 0.01 to 9.99 litres.
3.2.7. ‘b’ Settings. Air Detection, End of Delivery Flag, and Price Per Litre Display
These two options are available from Software Version 27:02:0:
°configurable air detect;
°Flag preset end of delivery.
This option is available from Software Version 27:130:0:
°Change price decimal point position.

3.2.8. Configuration Code
Since version 17 of the C3000 pump/dispenser software, the configuration code (used to set
the pump/dispenser to single, dual or multi mode) has been extended to 5 digits. When
configuring the pumps/dispensers, the litre display will display each digit, as shown in
Figure 3 on page 18.
NOTES:
1. For FUTRA software configuration options, see the FUTRA service supplement.
2. Multi-hosed Pump/Dispenser with LPG
An MPD with LPG is configured by setting digits 5=3 and 4=5.
With COM125 magnetic or Bennett meters, to set LPG compensation and motor spirit without
correction, set digit 1=4.
For COM125 optical meters when motor spirit correction is required as well, set digit 1=6.
Note: Software version 27070 and previous do not support LPG correction and motor spirit non-
correction, and require digit 4 for LPG and motor spirit 125 correction. This software should not
be fitted if the unit has COM125 magnetic or Bennett flow meters.
Setting the Configuration Code
Refer to section 3.2.1 page 13. While setting the configuration code, the price display shows
'C' and the volume display shows 'XXXXX'.

3.3. Further Settings Available on the ‘K’ factor Switch
The following configurations (K-Factor) switch settings are only available for CNG
dispensers, LPG dispensers, or bulk meter registers. As they are reasonably uncommon,
they have not been included in sequence with the four more common settings.
These 'uncommon' settings are:
•Density Factor 'dSF' - CNG (need appropriate software)
•Specific Density 'den' - LPG (need approriate software)
•Temperature'E'- LPG (with appropriate software) - Bulkmeter
•ACV Valve Flow rate 'FLO' - Bulkmeter
•L Cut 'L' - Bulkmeter
•H Cut'H' - Bulkmeter
•F Cut 'F' - Bulkmeter
Also for CNG, NOTE:
•With CNG, no-flow delay has no application and, this setting should be left set as
'n0000'.
•CNG uses the symbol 'SP' for setting display resolution instead of the normal dispenser
display resolution symbol 'Sr'
•The setting of decimal places 'SP' is used in some foreign countries with different
currencies. For New Zealand and Australia, leave this set to two decimal places (e.g.
'0.00').
3.3.1. Product Density Factor
This setting is only available for CNG dispensers.
The setting of the product density factor 'dSF' 'X.XXXX' is necessary for the C3000 to
accurately meter and display CNG dispensed in normal cubic meters (nm3). If the density
factor is set to ‘1.0000’, then the unit of the displayed amount dispensed is in kg.
The density factor displayed is actually the inverse of the density. The density factor is in
cubic metres per kilogram (e.g. If the display reads ‘0.8200’, this represents a density factor
of 0.8200 m3/kg). Similarly, the units displayed could be litres (equivalent of petrol) by
entering a conversion value as the Density Factor.
NOTE: For two hose (dual) dispensers, a Density Factor must be set for each hose.
Setting the Product Density Factor
Refer to section 3.2.1 page 13. While setting the Product density factor, the price display
shows 'dSF' (‘dFb’ for side “B”) and the volume display shows 'X.XXXX'.
3.3.2. Specific Density
This setting is only available for LPG and Bulkmeter modes
The specific density for LPG must be set to allow the C3000 to accurately meter the amount
of LPG dispensed. The specific density of the product should be obtained from the LPG
supplier, and must be entered in units of kg/m3.
Setting Specific Density
Refer to section 3.2.1 page 13. While setting the Specific Density, the price display shows
'dEn' and the volume display shows 'XXX.X'.

3.3.3. Temperature Calibration
Only available for LPG and Bulk-meter modes and only if the Temperature Compensation
PCB is installed and temperature compensation configured as detailed in Section 3.2.8
To set the temperature, place the probe in product of a known temperature. Allow 10
minutes for the probe temperature to stabilise, then adjust the temperature setting in the
register 'EXXX.X' to the known temperature value.
To check operation of the probe, press the 'K' factor switch to observe 'EXXX.X' and allow
the display to return to normal. Warm the probe and recheck the K-Factor switch
temperature setting. The new temperature should be displayed.
NOTE: The temperature is not updated while it is being displayed.
Setting the Temperature
Refer to section 3.2.1 page 13. While setting the temperature, the price display shows 'E'
and the volume display shows 'XX.X'. The temperature is displayed in °Celcius.
3.3.4. ACV Valve Flowrate
This is only available in Bulk Meter mode where the ACV Valve has 'Compac Designed'
controls. The Configuration code must be set-up for “Compac flow modulation” (4th digit
set to 2. Refer Figure 3 page 18)
Setting ACV Valve Flowrate
Refer to section 3.2.1 page 13. While setting the ACV Valve flowrate, the price display
shows 'FLO' and the volume display shows 'rXXXX'. The desired flowrate for the system
must be entered in litres per minute.
3.3.5. L-Cut
This is only available in Bulk-meter mode.
This value is similar to the preset cut-off used in a standard dispenser. Prior to the delivery
reaching its preset amount, the solenoids are switched to give a low flowrate. The “L-Cut”
sets the amount (in litres), prior to the preset amount being attained, at which the solenoids
will switch to a low flowrate.
Setting ACV Valve Flowrate
Refer to section 3.2.1 page 13. While setting the “L-Cut”, the price display shows 'LCUT'
and the volume display shows 'LXXXX'.
3.3.6. H-Cut
This is only available in Bulk Meter mode.
This value is the desired cut-off point to half flow (in litres) for the system. The “H-Cut” sets
the amount (in litres), prior to the preset amount being attained, at which the flowrate of the
system will be halved.
Setting H-Cut
Refer to section 3.2.1 page 13. While setting the “H-Cut”, the price display shows 'HCUT'
and the volume display shows 'HXXXX'.
